Product Description:

The CSH01.3C-SE-ENS-EN2-CCD-L2-S-NN-FW is a motion-control card supplied by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in multi-axis drive cabinets, the module issues velocity and torque references to servo inverters, coordinates axis positions, and integrates safety logic for production machinery with real-time operating requirements. Its control functions are suited for packaging, handling, and other synchronized automation tasks that depend on stable communication between multiple axes.

The controller operates from a base supply of 24 VDC for its logic circuits, and startup transients are limited to an inrush current of 4 A. Motion commands are exchanged over the SERCOS bus, where a minimum cycle time of 250 µs supports fine current-loop timing, while a transfer rate of 16 MBaud supports high-bandwidth parameter exchange. Internally, power stages can switch at up to 16 kHz, which supports motors that require elevated electrical frequencies. As the network master, it manages cross-communication based on IEEE 802.3, while the deterministic SERCOS ring carries the primary motion data. Two sensor channels are available: the ENS path accepts HIPERFACE, EnDat 2.1, or 1 Vpp encoders and supplies 11.6 VDC with 500 mA available, while the EN2 path supports EnDat 2.1, 1 Vpp, or 5 V TTL devices powered by 5 VDC.

The integrated safety circuit is connected through a D-Sub 9 Female connector and provides the certified Safe Torque Off function, which removes drive energy without interrupting feedback acquisition. For time-critical machine stops, the module can accept control pulses as short as 100 ms, allowing rapid drive shutdown even at maximum switching frequency. This arrangement lets one rack slot handle motion control, device monitoring, and safety isolation while keeping wiring concentrated at the controller level.
